IPC: C09D175/00
Filed: 1978-01-24
Abstract: PURPOSE: The title composition capable of giving tough films having improved weatherability, comprising  a resin obtained from an acrylic copolymer having carboxyl group in the side chains and a straight-chain monoepoxyalkane, and a polyisocyanate.

Title: Converging lens for optical disk
Inventor: YAMANAKA YUTAKA
IPC: G11B7/1392
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To realize a converging lens used for an optical head capable of recording and reproducing optical disk media having substrates different in thickness, in an optical disk device like CD, etc. SOLUTION: In the converging lens 3 to converge a beam exited from a laser light source 1 into a small spot, the lens surface of the converging lens for an optical disk is split into a plurality of areas sufficiently small compared with the lens aperture, and a first lens surface 4 forms a small spot on a first optical disk 6, while a second lens surface 5 forms a small spot on a second optical disk 7. Since each lens can be optimized independently, this enables an easy design. Thus, a piece of a lens can form two kinds of beam spots, which can cope with optical disks with substrates of different thickness.

Inventor: KONO TERUHISA
IPC: B60T8/48
Filed: 1989-01-13
Abstract: PURPOSE:To reduce the number of working solenoid valves by setting up a cutoff valve between a pressure source and a branch point and both first and second selector valves between the branch point and each wheel brake, respectively, in a device which impresses a pressurized fluid to these first and second wheel brakes by way of the branch point. CONSTITUTION:In a device which feeds both first and second wheel brakes 42, 43 with hydraulic pressure produced in a pressure source 40 by way of a branch point 41, a cutoff valve 45 being made into a state of being cut off by current-energization is installed between this pressure source 40 and the branch point 41. In addition, both first and second selector valves 46, 47 are set up in a fluid passage between the branch point 41 and the wheel brakes 42, 43, and each of these valves 45-47 is controlled by an electronic controller 48. In this case, this electronic controller 48 outputs both exciting and nonexciting signals to the cutoff valve 45 at a constant duty ratio when either side of at least these wheel brakes 42, 43 has come to a state of being pressurized, while it is installed so as to regulate the said duty ratio according to the discriminated result of the number of wheel brakes under the pressurized state.

Title: Wide band amplifier circuit
Inventor: WAKAYAMA NOBUHIKO
IPC: H04N5/14
Filed: 1993-01-20
Abstract: PURPOSE:To attain a wide band amplification by providing plural transistor circuits in parallel so that currents running through a common load resistance can be branched, and turned to each correcter current, and providing a correcter voltage which is changed by each transistor base input. CONSTITUTION:A circuit constituted of transistors TR1 and 2, and the circuit constituted of transistors TR3 and 4 constitute a drive circuit using a resistance R1 as the common load resistance. Then, a diode serially connected with the load resistance R1 prevents the cross over distortion of TR 23 and 24. A signal S1 is inputted to the base of each TR2 and TR4, and the correcter currents of each TR1 and TR3 are changed by the signal S1. At that time, the R1 and X1 are common to the TR1 and TR2, and the running currents are branched as the correcter currents of each TR1 and TR3. The input signal S1 is common, and the branch rate is almost decided according to the rate of the emitter resistances R2 and R3 of the TR2 and TR4. Thus, even when the load resistance is reduced, the same drive voltage as the conventional one can be obtained, and a frequency band can be enlarged.

Title: Mass spectrometer
Inventor: SHIZUKUISHI KENICHI
IPC: G01N27/62
Filed: 1993-01-20
Abstract: PURPOSE:To make the analysis of samples of different polarities without re-assembling an ion source by ionizing a sample of high polarity by an atmospheric pressure ion source from the rear part of an electron bombarding ion source for ionizing a sample of no polarity, and by guiding the sample ions. CONSTITUTION:A sample of no polarity flowed out of a gas chromatography 1 is ionized by electron bombarding ion sources 2-6, and is guided into an analysis part by a ripeller electrode 4. A sample of high polarity flowed out of a liquid chromatography 12 is ionized by atmospheric pressure chemical ionization ion sources 8-11 provided in the rear of the electron bombarding ion source, and by electrospray-ion sources 13-15. The trajectory of the sample ions emitted from each ion source is changed by a deflector electrode 7, and the sample ions are fed to a guiding analysis part from the rear part of the electron bombarding ion source in the direction of the ripeller electrode 4. Samples of no polarity to high polarity can thus be achieved without re-assembling the ion source.

Abstract: PURPOSE:To use phosphorus easily both in an n<-> layer and an n<+> layer, and to reduce a short channel effect in a MOS transistor having LDD(Lightly Doped Drain) structure by forming polysilicon by vapor growth (CVD) at a fixed temperature and burying the polysilicon in a gate electrode in a self-alignment manner. CONSTITUTION:An SiO2 film 19 is formed through a CVD method, and patterning using a resist 20 is conducted to a shape including a gate electrode 14. In the patterning, SiO2 films 21 are left on both sides of the gate electrode 14, and opening sections 22 are shaped. When polysilicon 23 is formed on the whole surface through the CVD method and etched in response to the opening sections 22, the opening sections 22 are formed in structure in which they are buried with polysilicon 23, and shaped in a self-alignment manner to the gate electrode 14. Phosphorus is ion-implanted through polysilicon 23, thus forming n<+> layers 17. Accordingly, a short channel effect can be reduced in a MOS transistor having LDD structure, and phosphorus can be employed for shaping the n<+> layers.

Title: Pulse generator for memory circuit
Inventor: ROBAATO CHIIFUUN UON
IPC: H03K3/0232
Filed: 1992-01-20
Abstract: PURPOSE: To provide a timer for a memory array utilizable for on chip timing measurement with high accuracy without the need of an additional circuit. CONSTITUTION: Relating to an adjustable delay element incorporating a reference generator and the half of a bipolar SRAM cell, in an operation, the rising edge part of an incoming clock pulse CLK 18 sets a receiver/latch 11 and latches an internal clock ICL (that is, a write clock) 30. The same rising edge part of the clock pulse 18 also performs the function of starting the changeover of the half memory cell of an adjustable delay part 14. When the half memory cell is switched to the second state to the half (relating to the reference generator), the latch is turned to an inactive state and an ICL write pulse 30 is lowered. Thus, the ICL write pulse 30 is automatically timing adjusted and the operation becomes possible by the actual memory cell.

Abstract: PURPOSE: To obtain anti-akid control by permitting the pressure, which is controlled by an anti-skid control system used for a signal brake system, as pilot pressure for effecting pressure control within a wheel brake of another brake system.  
     CONSTITUTION: When an about-to-skid state of wheels occurs, a pneumatic directional control valve 200 is switched, whereby atmospheric air is introduced into a right chamber 115 of the actuator to cause a power piston 113 to be moved to the left with the pressure difference with respect to a left chamber 114. A reducing piston 111 is moved to the left with the pressure within a pressure reduction chamber 112 to increase the volume of the pressure reducing chamber. The pressure within the pressure reducing chamber is transmitted through a control valve 400 to a wheel brake 13a to reduce the braking force of the wheel brake 13 and also constitute the pilot pressure of a wheel brake 15a.
